l skeleton, were tested for their anti-tumor-promoting activity using a short-term in vitro assay for Epstein-Barr virus early antigen (EBV-EA) activation. All these compounds were more active than their linear or saturated reference compounds in inhibiting the EBV activation promoted by the tumor promoter 12-O-tetradecanoylphorbol-13-acetate (TPA), the diester 1-O-(4-methylpentanoyl)-2-O-[6-O-(4-
测试了六个新的半乳糖甘油类似物,其中一个或两个4-甲基戊酰基或反-2-丁烯酰基与2-O-β-D-半乳糖基甘油骨架相连,并通过短期测试了它们的抗肿瘤活性EB病毒早期抗原(EBV-EA)激活的体外测定。所有这些化合物在抑制肿瘤启动子12-O-十四烷酰phorbol-13-乙酸酯(TPA),二酯1-O-(4-甲基戊酰)-2-促进的EBV活化方面均比其线性或饱和参照化合物更有活性。直到现在测试的O- [6-O-(4-甲基戊酰基)-β-D-吡喃半乳糖基] -sn-甘油产生最活跃的糖脂类类似物。在体内两阶段致癌性试验中测试时,四种化合物(三种丁烯酸酯和一种4-甲基戊酸酯)还表现出对小鼠皮肤肿瘤促进作用的抑制作用。
